Question

Why should people implement rainwater harvesting?

• A. To pass time
• B. To use it during scarcity of water
• C. To play with water
• D. To pour the rain water directly to the sewage

Answer 1

The correct option is B To use it during scarcity of water

Rainwater harvesting helps to store the rainwater so that it can be used during the scarcity of water. As per our requirement, we can either use it directly or to recharge groundwater because the rain falling on the surface from the rooftops flows away rapidly.
